Temperature TagThe Temperature Tag uses a high-accuracy temperature sensor TMP112 with a typical accuracy of ±0.1 °C at 25 °C. This sensor is digital and calibrated. It communicates using an I²C bus and features a very low power operation and shutdown mode.

Features

  • Integrated temperature sensor TMP112 (TI)
  • Communication using I²C bus
  • Temperature accuracy (typical values):
    • ±0.1 °C at 25 °C
    • ±0.25 °C in the range from 0 °C to 65 °C
    • ±0.5 °C in the range from -40 °C to 125 °C
  • 12-bit resolution (0.0625 °C)
  • Optional interrupt output
  • Power consumption:
    • 7 µA active current (4 Hz sample rate)
    • 0.5 µA shutdown current
  • Operating voltage range: 1.4 V to 3.6 V
  • Operating temperature range: -40 to 125 °C
  • Mechanical dimensions: 16 x 16 mm
